Insights

Elevated lipoprotein(a) (Lp(a)) levels are linked to a higher risk of pediatric arterial ischemic stroke (AIS). This finding highlights the importance of measuring Lp(a) in children diagnosed with AIS.

Area of Science:

  • Neurology
  • Cardiology
  • Pediatrics

Background:

  • Pediatric arterial ischemic stroke (AIS) is a rare but severe condition.
  • Elevated lipoprotein(a) (Lp(a)) is a known risk factor for stroke in adults.
  • Data on Lp(a) and pediatric AIS is limited, necessitating further investigation.

Purpose of the Study:

  • To evaluate the association between lipoprotein(a) levels and the risk of arterial ischemic stroke in children.
  • To determine if elevated Lp(a) is an independent risk factor for pediatric AIS.

Main Methods:

  • A case-control study was conducted involving children (≤18 years) diagnosed with AIS.
  • Participants were divided into neonates and children older than 29 days.
  • Cases were matched with controls for age at Lp(a) testing and sex; multivariable logistic regression was employed.

Main Results:

  • Children with AIS showed a higher prevalence of Lp(a) levels >50 mg/dL compared to controls (21.7% vs. 3.2%).
  • A significant positive association was found between Lp(a) levels and AIS risk (OR: 1.36 per 10 mg/dL increase).
  • Adjusted analysis confirmed the association, considering age, BMI, and measurement assay.

Conclusions:

  • Elevated Lp(a) levels are positively associated with an increased risk of AIS in children.
  • High Lp(a) may represent an independent risk factor for pediatric AIS.
  • Lp(a) measurement is crucial for children presenting with AIS.
